| 摘 要： | 文章采用等标污染负荷的评价方法对梁子湖湿地水体的化肥污染、畜禽粪便污染、精养鱼塘污染进行了评价。评价结果表明:TN和TP的排污量分别高达1276.49t和102.95t;污染源总的等标排放量TN、TP分别为12.76×108m3、5.15×108m3。化肥TN的排污量最高;精养鱼塘TP的排污量最高。针对不同的污染源,提出了初步的控制对策和措施。

| Abstract: | An investigation was conducted for estimation of loadings of non-point source of nitrogen and phosphorus in the lake's catchment,including the loadings from livestock,applying chemical fertilizer and intensive-breeding fishponds.According to the study,chemical fertilizer contributes most of the load for nitrogen and fish breeding for phosphorus.Countermeasures against eutrophication of Liangzi Lake are also put forward. |
